Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the RFS0G101MCN1GS are determined by the following allowed parameters:

Upgrade Substitutes (Higher voltage rating, same or compatible electrical characteristics):

• RFS0J101MCN1GS and PCJ0J101MCL1GS: Both rated at 6.3 V with identical 100 µF capacitance, ±20% tolerance, 24 mOhm ESR, and 2000 hour lifetime at 105°C. These parts provide voltage margin improvement while maintaining the same physical footprint and surface mount land size.
• APXE6R3ARA101ME61G: Chemi-Con equivalent rated at 6.3 V with matching electrical specifications (100 µF, ±20%, 24 mOhm ESR, 2000 hour lifetime). Same physical dimensions and land size.

Similar Substitute (Same voltage rating, alternative manufacturer/series):

• PCF0G101MCL4GB: Nichicon PCF series rated at 4 V with identical 100 µF capacitance, ±20% tolerance, and 22 mOhm ESR. Physical dimensions differ slightly (0.248" diameter vs. 0.197", 6.30 mm vs. 5.00 mm), requiring PCB layout verification.

All substitutes maintain the same capacitance value, tolerance, operating temperature range, and general purpose application suitability as the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Same Series): PCF0G101MCL4GB is a direct electrical equivalent within the Nichicon product line at 4 V rating. However, the increased physical diameter (6.30 mm vs. 5.00 mm) and larger land size (6.60 mm x 6.60 mm vs. 5.30 mm x 5.30 mm) require PCB layout verification before implementation. This part is REACH Affected, which may impact supply chain compliance requirements.

For Voltage Margin Upgrade: RFS0J101MCN1GS is the preferred upgrade substitute, maintaining the same FPCAP/RFS series designation as the main part with REACH Unaffected status. The 6.3 V rating provides voltage headroom while preserving identical physical dimensions and land size. Slightly increased ESR (24 mOhm vs. 22 mOhm) and ripple current specifications remain within acceptable operating parameters.

For Cross-Manufacturer Sourcing: APXE6R3ARA101ME61G (Chemi-Con NPCAP-PXE series) provides a 6.3 V upgrade option with REACH Unaffected status and identical physical footprint. This part enables supply chain diversification while maintaining electrical and mechanical compatibility.

For Alternative Nichicon Series: PCJ0J101MCL1GS (Nichicon PCJ series) offers 6.3 V rating with matching electrical specifications but is REACH Affected. Height difference (6.00 mm vs. 5.70 mm) requires clearance verification in space-constrained applications.

All substitute parts maintain active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RFS0J101MCN1GS replace RFS0G101MCN1GS directly on the PCB? A: Yes. RFS0J101MCN1GS maintains identical physical dimensions (0.197" diameter, 5.70 mm height) and surface mount land size (5.30 mm x 5.30 mm). The 6.3 V rating is a voltage upgrade that does not affect mechanical compatibility. No PCB layout changes are required.

Q: What is the difference between the upgrade substitutes? A: RFS0J101MCN1GS and APXE6R3ARA101ME61G are physically and electrically identical (both 6.3 V, 100 µF, 24 mOhm ESR). The primary difference is manufacturer: Nichicon versus Chemi-Con. PCJ0J101MCL1GS is also 6.3 V but has a slightly taller profile (6.00 mm vs. 5.70 mm), requiring height clearance verification.

Q: Why does PCF0G101MCL4GB have a different physical size? A: PCF0G101MCL4GB belongs to a different Nichicon product series with a larger can diameter (6.30 mm vs. 5.00 mm) and correspondingly larger land size (6.60 mm x 6.60 mm vs. 5.30 mm x 5.30 mm). PCB layout verification is mandatory before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts are ROHS3 compliant. However, PCJ0J101MCL1GS and PCF0G101MCL4GB are REACH Affected, while RFS0G101MCN1GS, RFS0J101MCN1GS, and APXE6R3ARA101ME61G are REACH Unaffected. Supply chain compliance requirements should be evaluated based on application jurisdiction.

Q: What is the ESR difference between the main part and upgrade substitutes? A: The main part RFS0G101MCN1GS has 22 mOhm ESR. All upgrade substitutes (6.3 V rated) have 24 mOhm ESR. This 2 mOhm increase is within typical polymer capacitor tolerance and does not affect general purpose application performance.

Q: Can I use a 6.3 V rated part in a 4 V circuit? A: Yes. A higher voltage rated capacitor can be used in lower voltage applications. The 6.3 V parts provide voltage margin and are electrically compatible with 4 V circuits. No circuit modifications are required.

Q: Which substitute offers the best inventory availability? A: RFS0J101MCN1GS has the highest inventory level at 7,435 pieces. APXE6R3ARA101ME61G has 2,270 pieces, PCJ0J101MCL1GS has 2,194 pieces, and PCF0G101MCL4GB has 2,006 pieces.
